Re: Need better gas mileage and performance
when your talking performance not much is cheap
tbi is the best for fuel economy but not with a 3 speed auto your best bet would be to find a newer truck with the nv4500 1996-2000 have better ratios and every gear is sencronised and all the power gets put to the ground insted of being lost threw the tq converter and the soft shifts the exhaust cats coust quite a bit i would leave the factry one on and get a more free flowing muffler efi with the cat will pass smog a cold air intake like k&n only buy it once clean it a million times best way to go if you wana save money
